The entire workflow is 100% freeware, from the plugin to the final render, making it an excellent choice for those on a zero budget. The main trade-off is its workflow, which involves an export-render round trip rather than a live link. This means you must export your scene from SketchUp each time you want to see updated changes in Kerkythea. However, for designers patient enough to learn its settings, it can produce high-quality images of furniture pieces and interior spaces that rival paid software, especially given its extensive community-supported material libraries.
Our Take: Kerkythea is a fantastic option for users who prioritise cost above all else and are willing to accept an older user interface and a more traditional workflow. It’s a powerful learning tool and can still produce professional-quality visuals for a furniture catalogue or portfolio if you invest the time to master its settings. Its dated interface is the biggest hurdle, but the quality of the final output remains impressive for a freeware tool.

The licensing model is exceptionally generous; Twinmotion is completely free for students, educators, hobbyists, and any company earning less than $1 million in annual gross revenue. This makes it a powerful, no-cost option for startups and independent designers. Its one-click material applicators, weather presets, and extensive asset library mean you can quickly stage a furniture piece, like a new armchair, in a believable interior or exterior setting. The real-time path tracer provides instant feedback on how light interacts with your materials, which is crucial for achieving realism.
Our Take: Twinmotion is an ideal choice for those who need fast, impressive visualisations without the steep learning curve of a full game engine. Its generous free licence removes barriers for smaller furniture businesses and freelancers. While it offers less granular control than Unreal Engine, its speed and intuitive workflow make it perfect for rapid prototyping and client presentations.
Unreal Engine is a powerhouse real-time engine, offering an incredibly high ceiling for visual fidelity, and it’s a compelling piece of free render software for SketchUp, particularly for complex scenes or interactive presentations. While known for video games, its use in architectural and product visualisation is completely free. The workflow relies on the Datasmith Exporter plugin, which efficiently transfers your SketchUp Pro models, including geometry, materials, and metadata, directly into the Unreal Engine editor for final texturing, lighting, and rendering.
Unreal Engine + Datasmith Exporter for SketchUp
The primary advantage of this pipeline is scalability. You can start with photorealistic still images of a furniture piece and then expand the project into a fully interactive virtual reality (VR) walkthrough of a showroom or a cinematic animation, all within the same software. Features in Unreal Engine 5, like the Lumen real-time global illumination system, provide stunningly realistic lighting that reacts instantly to changes. This makes it ideal for visualising how a new sofa collection would look under different lighting conditions in a complex interior scene.
Our Take: Unreal Engine is the ultimate choice for those who need more than just static images and are willing to invest time in learning a more complex tool. The visual quality is second to none, but the steep learning curve makes it less suitable for quick, simple renders. It’s important to note the Datasmith plugin requires SketchUp Pro, so it's not a viable workflow for users of SketchUp Free or Make.
NVIDIA Omniverse is an advanced real-time collaboration and simulation platform, positioning itself as a powerful piece of free render software for SketchUp for technically inclined users. Aimed at professionals building complex, collaborative workflows, it leverages NVIDIA's RTX technology for stunning real-time path-traced rendering. The platform uses the open Universal Scene Description (USD) format, and its SketchUp Connector allows designers to sync their models into this powerful ecosystem for visualisation and co-creation. This makes it an intriguing option for studios working on large-scale interior projects or complex furniture assemblies.
NVIDIA Omniverse (SketchUp Connector)
The primary appeal for individual users is that Omniverse is free for personal and creator use. This provides access to enterprise-grade technology, including its Nucleus server for live collaboration and its suite of creator apps. For furniture designers, this means you can bring a SketchUp model into Omniverse and apply physically accurate materials, lighting, and environments with photorealistic results powered by an RTX graphics card. The live sync means changes to your chair or table model in SketchUp can be updated in the Omniverse scene almost instantly.
Our Take: NVIDIA Omniverse is a forward-looking choice for Windows users with NVIDIA RTX hardware who are interested in a future-proof, collaborative pipeline. It has a steeper learning curve than most renderers, but its power is undeniable. The Connector is still evolving, but for those willing to invest time, it offers a glimpse into the next generation of 3D workflows, completely free of charge.

The platform's main advantage is its speed and extensive, high-quality content library. You can quickly populate a furniture scene with realistic people, plants, decor, and lighting presets, which is ideal for rapidly exploring different layouts and atmospheres. This makes it a great tool for digital product staging where speed and context are key. The trade-off for the free educational license is a small, non-obtrusive watermark on all exported images and videos. For professional, commercial work, a paid license is required.
Our Take: Lumion is a fantastic option for students or professionals wanting to train and build their portfolios without initial investment. Its speed and vast asset library make it one of the fastest ways to go from a simple SketchUp model to a fully realised environment. However, the watermarks and non-commercial restrictions on the free version mean you’ll need to upgrade for professional projects.
